ROTARY TIPPLER FOR USE IN DISGHARGING COAL 03 OTHER MINERAL FROM I-IUTCI-IES, CORVES, OR THE LIKE.

To all whom it may concern:

Be it known that I, JOSEPH DODDS, a subject of the King of Great Britain, residing at Rutherglen, Glasgow, Scotland, have invented certain new and useful Improvements in Rotary Tipplers for Use in Discharging Coal or other Mineral from Hutches, Corves, or the Like, of which the following is a specification.

This invention relates to rotary tipplers or tipples for use in discharging coal or other mineral from the hutches, corves or such like within which it is conveyed.

The object of my present invention is to provide a rotary tippler wherein the necessity for employing the usual creeper or drag for drawing the hutches is obviated and wherein the discharging and righting operations are automatically and rapidly performed.

Under this invention the hutches are turned downward through a half revolution so as to discharge their contents and are thereafter raised upward through a second half revolution in such manner as to again right them and at the same time bring them to a level higher than their level on entering the tippler, the power for raising the empty hutches to the higher level being obtained from the loaded hutches and the coal discharged therefrom.

In order that the invention may be clearly understood, I have hereunto appended eX- planatory drawings which show, by way of illustration or example, one mode of carrying out the invention.

On the said drawings z-Figure 1 is a side elevation of the rotary tippler. Fig. 2 is an end view thereof.

The rotary tippler shown on the drawings is made in two parts, a discharging device a and a righting device 6, the loaded hutches a entering the discharging device from the inclined rails d while the empty hutches 0 pass from the righting device to the inclined rails (Z The discharging device is made with a horizontal shaft 1 mounted in bearings 2 and having secured thereon a rectangular frame 3 upon which are mounted four sets of rails 4, each rail being made double, as usual in rotary tipplers, so as to provide a running surface for the wheels while 7 for limiting the movement of the rails 4: is hinged, at 5, to the said frame 3 at the Specification of Letters Patent.

entrance end of the discharger and, at the exit end of the same, there is provided, on the frame 3, a projection 6 having a head 7 for limiting the movement of the rails l outward from the shaft 1. Secured to each set of rails 1 is an inclined plate 8 of rectangular form or the equivalent thereof, and suitably mounted at the side of the discharging device is a stationary chute 9 of channel formation having its upper part curved to conform to the circle described by the plates 8 which project thereinto while the lower part of the chute is so formed as to direct downward the coal supplied thereto from the hutches being discharged. The shaft 1 of the discharging device has secured thereon, at the entrance end of the device, a brake wheel 10 adapted to be engaged by a friction band 11 which may be tightened on the wheel by means of a hand lever 12, and located between the ends of the rails (Z is a slidingbolt 13 which may be moved by means of a hand lever 1 1 into or out of the path of a number of projections 15 provided on the end of the frame 3, one adjacent to each set of rails 1, so that, when the bolt 13 is in its operative position, the discharger is held with a set of rails 1 in position to receive a hutch from the rails (Z. The sets of rails in the upper part of the discharger lie axially of the shaft 1 and as they move to the bottom of the discharger they turn on their hinges 5, the exit ends being stopped by the heads 7 so that the rails 4: lie at an angle and the hutches 0 may run therefrom by gravity. The righting device 1) receives the inverted and discharged hutches which run from the discharging device.

The righting device I), which is arranged in line with the discharging device a, consists of a horizontal shaft 16 mounted in bearing brackets 17, and driven by means of a gear wheel 18 thereon from a gear wheel 19 on the shaft 1 of the discharging device, and secured on the shaft 16 between the brackets 17 is a frame .20 carrying four sets of rails 21 arranged at a slight angle to the shaft 16, in such manner that the hutch 0, carried in the set of rails for the time being lowermost, may run therefrom over bridge rails 22 mounted upon pedestals 23 and into the set of rails for the time being lowermost in the righting device while the discharged and righted hutch for the time being uppermost in the righting device may run therefrom on to the rails (Z Suitable means may beprovided for preventing a loaded hutch leaving the rails (Z before a set of rails is in position to receive the same, and means are provided for preventing a hutch from leaving the discharg ing device before it has reached the lowermost position or from leaving the righting .device before it has reached the uppermost position.

In operation, the attendant withdraws the bolt 13 from the path of the projections 15 by means of the hand lever 14 and operates the brake lever 12 so as to release the shaft- 1 and the discharging device is caused to rotate in the direction of the arrow, Fig. 2, by the weight of the loaded hutches in the discharger. As the device rotates the contents of the hutches are discharged on to the plates 8 in the chute 9 and, by acting on the plates assist in the rotation of the device, and as each discharged hutch reaches the lowermost position in the discharging device the rotary motion is stopped by means of one of the projections 15 which engages the bolt 13. Each time the rotary motion is arrested in this manner a loaded hutch is run on to the uppermost rails %t and at the same time the lowermost .rails 4t turn on their hinges 5 and take up an inclined position while the inverted and discharged hutch thereon runs down on to the lowermost set of rails 21 in the rotary righting device Z). The rotary motion of the discharger a being transmitted to the righter 6 through the gear 18, 19, the discharge hutches on being received by the righting device at the bot tom thereof are raised upward in a semicircular path while being righted and as they reach the uppermost position in the righting device they are permitted to run from the rails 21 on to the inclined railway (Z the operation being thus automatically continued, a loaded hutch being supplied to the tippler and an empty hutch being supplied therefrom at each quarter of a revolution made by the tippler.

The device a may itself be used as a discharging and righting device, the hutches in this case being caused to make a complete revolution therein. As each empty hutch comes to the top it is removed and its place taken by a loaded hutch.

Having now fully described my invention what I claim and desire to secureby Letters Patent is z.
